Interesting, thanks Hadley. I have to say I have moved most of my advanced graphics to ggplot2 and my users absolutely love it. Yes I bought your book several years ago. Here is an example of a complex plot of mine that successfully uses a 2d-plane but multiiple dimensions of data, using your excellent library. We are able to put a large amount of data, with multiple obliquely related distributions, all on the same plot. The thick white lines represent a 2-z score fwiw. As you will gather, we are thereby able to superimpose to related but not linearly correlated distributions both on the sample, plot, using colour to represent cheapness or dearness, and having both basis point and z-score based visualization. One stop relative value shop, thanks to ggplot2 ;-) http://stackoverflow.com/questions/24828341/how-do-i-remove-the-printed-output-warnings-using-ggplot2-with-knitr http://stackoverflow.com/questions/24828341/how-do-i-remove-...
